Thank you for describing the methodology of 2015 Best Engineering Schools Rankings. I find this ranking very helpful. I was particularly pleased to find that my department’s rank has grown significantly this year. However, I would like to share my concern about one particular matter. In estimating the research activity of faculty, the amount of research expenditures was the only parameter taken into consideration. However, scientific research is about making scientific discoveries and not necessarily about making money. The importance of the discoveries, the depth of the ideas and the lasting impact on the scientific field (which is usually described by citation metrics) all matter for estimating the quality of research. I strongly suggest to take into consideration the quality of publication and citation for your next year’s ranking, as many other ranking systems do (you can contact me for more information if you are interested to know how others measure research impact). Presenting the amount of money spent as the only parameter characterizing the quality of research sends a wrong message to university administrators, such as Deans and Department Chairs.
